Open House 2014, a concept developed in London twenty two years ago which has now spread to cities across the world, will throw open the doors to some of the UK capital's most inspiring spaces and interiors this month. "Revealing", the theme of this year's Open House, intends to "shed light on issues that are relevant to local communities." In this way, the scheme hopes to examine how the built environment is evolving. Exploring the role of architects, engineers and contemporary design in revitalising places and spaces, the festival hopes to show above all "how good design can make London a more livable, vibrant and enjoyable city."
